DELPHI, Ind. -- While the families of two murdered Delphi teens have been devastated by their deaths, the case is also tough for the officers working tirelessly to bring them closure.
“People that look like me and dress like me are expected to almost look beyond that. People think that’s just part of what I do,” said State Police Superintendent Doug Carter. “I disagree with that.”
Abigail Williams, 13, and Liberty German, 14, went hiking on February 13, near the Monon High Bridge. A search team found their bodies the next day.
More than a week later police are still searching for their killer.
Carter said cases like this play on the emotions of everyone involved, especially the ones who have been closest to the crime.
“I’ll never be able to unsee what I saw that day,” said Carter.
Police released new details on Wednesday along with a short audio clip they say was recorded by Liberty the day she died.
They are asking anyone who recognizes the voice in that clip or who thinks they might have a clue, no matter how small, to contact them.
Carter said he believes that Liberty’s recordings will help them solve this case.
"One day I'm going to thank her," said Carter. "We wouldn't be here today without that photograph."
He is also determined to find the girls’ killer.
“I want to meet with their parents and tell them: Guess what? We did it,” said Carter. “I feel so strongly about this. I can’t imagine ending my life and not finding the guy who did this.”
